About Us

SDT Co., Ltd. (SMART DISPERSION TECHNOLOGY) is a technology company with the mission of "enriching life through new technology."

We identify outstanding technologies that have been proven worldwide but remain underutilized in Japan, then commercialize and distribute them to society. As both "discoverers" and "deliverers" of technology, we aim to transform daily life and business operations.

Our flagship product — a liquid fuel combustion accelerator based on a technology born in Japan half a century ago — is powered by the latest molecular dispersion processing technology. It is compatible with all liquid fuels (gasoline, diesel, kerosene, and heavy oil) and simultaneously achieves improved fuel economy, cleaner exhaust, and reduced equipment load.

The product's effectiveness has been numerically verified through JIS standard testing, and it is backed by international credibility — including US EPA certification and a track record of sales in Europe — as we advance our full-scale expansion into the Japanese market.

SDT will continue to discover "life-improving technologies" across energy, environment, health, materials, and other diverse fields, and deliver them to society.

Dispersion is what defines SDT — our greatest distinguishing trait and the field we specialize in above all else. How do we precisely disperse matter and energy? This is the question at the heart of everything we build. From liquid fuel combustion accelerators to broader systems and products, dispersion technology is what sets SDT apart.
